Since it's inception Quantum Devices has played a major role in the advancement of medical instrumentation. Our LEDs and detectors can be found in leading manufacturers glucometers and pulse oximeters. and photodynamic therapy investigational devices.

Photodynamic therapy (PDT) is a cancer treatment modality that recently has been applied to brain tumors, breast cancer, coronary artery disease, and skin disorders. PDT consists of intravenously injecting a photosensitizer, which preferentially accumulates in tumor cells, into a patient then activating the photosensitizer with a light source. This results in free radical generation followed by cell death. The development of more effective light sources for PDT has been facilitated by applications of space light-emitting diode array technology; thus permitting deeper tumor penetration and wider coverage area.
